WILLIAM HARTLEY PUGH, OF CINCINNATI, OHIO.

SPECIFICATION forming part of Letters Patent No. 792,289, dated June 13, 1905. Application filed February 23, 1905. Serial No. 246,983.

To (all whom, it may concern.-

Be it known that I, WILLIAM HARTLEY PUGH, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Mechanism for Constructing Concrete Falls; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improved mechanism for constructing concrete walls and buildlngs.

One of its objects is to provide simple and efficient means for constructing double concrete walls and carrying the construction thereof forward progressively in sections.

Another object is to provide efificient means for constructing walls of varying thickness and for varying the thickness at different parts of the wall.

Another object is to provide improved means for forming corners of any described angle, from which the walls may be projected as required.

It further consists in certain details of form, combination, and arrangement, all of which will be more fully set forth in the description of the accompanying drawings, in which Figure 1 is a vertical section through my improved mechanism on the wall in position for use on line o o of Fig. 2. Fig. 2 is a side elevation of the mechanism shown in Fig. 1. Fig. 3 is a top plan view of the mechanism employed in forming the corners. Fig. 4 is a sectional detail of the same on line m w of Fig. 3. Fig. 5 is a perspective view of one of the clamping-bolts.

In practice a corner A is first molded within the molding-frame B, which is composed of the sections 6 b c c to form an inclosure within which the concrete is molded to form the corner stone or block A. The sections 6 b are usually set at right angles to each other and provided with pivot-posts a a, which are adjustable horizontally along the face of the sections b d to determine the dimensions of the block A. Hinged to the posts a a are sections 0 0, their opposite ends being divided into fingers d, which interlock and are provided with holes (Z to receive a pin 6 to hold them to the adjusted position. In practice the fingers are made sufficiently narrow so that the concrete will not escape between them, and this may be further prevented by placing sheets of metal inside the sections to cover the openings between the fingers.

D represents an adjustable brace extending across between posts a and a, the same being composed of two sections provided with slots f and bolts f to lock the sections together after adjustment.

After the corner has been formed the walls are projected therefrom, as indicated in dotted line, Fig. 3, which is done in the case of a double wall by mounting the mechanism, Figs. 1 and 2, adjacent to the corner-block and after adjustment filling in the concrete and after this has set moving the mechanism forward or upward to form a new section. The double wall-sections E E are formed between side plates F F and G G, which plates are provided with T-shaped slides g, which engage and slide in correspondingly-shaped recesses g in the supports or uprights H. These uprights are each provided with an angle or cross bar H and seat in U -shaped crossframes I, to which the cross-bars H are clamped after adjustment by means of yokes K and set-screws K. One set of uprights H are preferably employed at each end of the plates E E G G, by means of which said plates are adjusted and held in the desired position. Below the edges of the plates the uprights are provided with adjusting-screws L, by means of which the uprights are adjusted and held the desired distance away from the previously-formed wall-section. The bolts 7 enable the slides g to be clamped to the uprights H after adjustment.

M represents a plate to close the opening between the plates across one end, the opening at the opposite end being usually closed by post A or a previously-formed wall-section. This plate M has shoes IV adjustable across its face and with recesses to receive the ends of slides g and bolts m to clamp the shoes thereto. The cross-frames I are preferably provided with notches 91 to retain the yokes K in a central position. \Vhere it is desired to form a single instead of a double wall, the plates F G and their uprights are removed and the wall formed between the remaining plates. N represents metal rods employed at intervals to tie the walls together. V here it is desired to reduce the thickness of the wall as it increases in height, this is effected at either side by means of the adjustable screws L. If desired, the face of one or more of the plates may be laid out in a design of any desired character to be impressed on the face of the wall.

The mechanism herein described is capable of considerable modification without departing from theprinciple of my invention.

Having. described my invention, what I claim is 1. In a mechanism of the character indicated, a series of uprights having horizontal arms, channel-frames supporting said horizontal arms, yokes to clamp the arms in the channel-recesses, and mold-plates supported upon said uprights.

2. In a mechanism of the character indicated, a series of uprights having horizontal arms, channel-frames adjustably supporting said horizontal arms, yokes to clamp the arms in the channel-recesses of said frames, moldplates supported by said uprights, and means for adjusting said uprights relative to the previously-formed wall-sections.

3. In a mechanism of the character indicated, a series of uprights having horizontal arms a cross-frame in engagement with said horizontal arms, yokes encircling said horizontal arms and the cross-frame to clamp the uprights to the cross-frame, mold-plates adjustably secured to said uprights and means for clamping said plates to their adjusted position.

4:. In amechanism of the character indicated, a corner-mold composed of an angleplate, pivot-posts adjustable relative thereto, plates hinged to said posts and provided at their free ends with interengaging fingers, and means for locking said fingers to varying positions of adjustment.

5. In a mechanism of the character indicated, an angle-plate, pivot-posts adjustable relative thereto, plates hinged to said pivotposts and provided at their free ends with interengaging fingers, means for locking said fingers to varying angles of adjustment, and a brace connecting the said posts.

In testimony whereofI have aiiixed my signature in presence of two witnesses.

WILLIAM HARTLEY PUGH.
